For at least a couple of decades, there has been a trend going around Catholic circles to "explore our Jewish roots." If this exploration was limited to interfaith dialogues between Jewish and Catholic theologians, or even to friendly discussions between Jews and Catholics, there wouldn't be a problem. Dialogues and discussions can be helpful, even praiseworthy. The trouble starts when lay Catholics decide to "try out" Jewish ritual.

"We run no risk of deceiving ourselves in considering a Superior Intelligence the author of all things, in referring to it those splendors of the heavens which aroused our thoughts; and finally we are ready to understand and accept the traditional formula: God, Father Almighty, Creator of heaven and earth."
